Got it. Thanks You're right, it was a bit hard to follow. I selected each item individually, roads first, and converted back to a polyline. Once I converted the roads I was able to do the same to the terrain line and then delete it. I had been staring at the screen too long and missed the obvious. What was throwing me off was that if I converted the terrain line to a polyline first then the roads disappeared but converting the roads first had no effect on the terrain line. Either way, I eventually got there.

I am working on my first detailed site plan and am having an issue deleting out a terrain line. I had finished the as-built for the house and drew the site plan from a jpeg that I imported from the county GIS site. Once the site plan was done I made a copy and rotated the copy into place. In hindsight I shouldn't have worried about the copy but I like to have a backup the first time I do something. The site plan includes terrain perimeter, contours, and the surrounding roads. My issue is... I was able to delete the roads on the first site plan (the one not rotated into place) but when I delete the polyline that was set as my terrain perimeter it deletes some of the items (roads and the drawn contours) that are part of the final site plan. I am not able to set the terrain perimeter of the final site plan until I delete the first site plan. Is there a way to convert the terrain perimeter back to a CAD polyline so that it is no longer "attached" to the other items and then delete? As I said, this is my first trip down this path so I am having a hard time wrapping my head around why the original terrain perimeter is attached to the roads in the final plan. Oh, and i butchered the original plan trying to delete it so deleting the new and rotating the original into place is not an option. I have a feeling this is a simple fix but I am not finding it. Thanks for any help.
